ABS Dynamic Simulation Test Stand using Lab View

Anti-lock braking system (ABS) is an automobile safety system for vehicles which will allow controlling wheels of vehicle and providing safety contact on road surface according to driver braking input, avoiding uncontrolled skidding and also preventing the wheels from locking up. The main task of ABS is to press and release the brakes almost 15 times a second, so process of stopping the vehicle in a shorter time and distance. The ABS controller basically prevents the braking wheel from skidding on the road surface. Because of all these features, ABS has greatly improved the performance of automobile security. Currently the test stand is used to take measurements and analysis of ABS. The ABS system performs two main functions, automatic measurement and testing of high quality ABS. In this paper, the test stand can create a virtual environment so that various testing conditions can be applied for ABS system. The test stand can record all the parameters and compare with stored values, and simultaneously apply for Lab View software. This Software is used to calculate varies parameters of the test stand and also generate graph which shows running status test stand.

Identifying & Mitigating Cyber Security Threats in Vehicular Technologies

In the past decade, technologies in vehicles have been rapidly advancing creating both a new type of “on the road” entertainment and safer environment while driving. Technologies such as anti-lock brake systems, steering assist, and in some cases autonomous driving, manufactures nearly eliminated the dangers of driving. To maintain the advances in safe technologies, it is vital to establish a strong security system for automotive networks and is crucial to advance the state of the art in automobile security. Motivated by this, one of the main goals of this research paper is to define a threat environment for CAR networks by discussing the existing security vulnerabilities and threats/attacks that an automobile network is currently facing. To address these security challenges, we also present a distributed firewall system to protect a CAR network from both internal and external networks.

Connected cars – the next targe tfor hackers

Not so long ago, the idea of us all motoring around in driverless and crash-proof cars seemed about as believable as the 1960s Jetsons cartoon family zipping around in their Aerocar. But today's petrol-heads are rapidly getting used to the fact that next-generation ‘connected' cars, whose wifi-like crash-avoidance systems beacon out to track nearby vehicles, will start appearing on our roads in 2017/18. Driverless and crash-proof cars are no longer science fiction but fact. They promise a revolution in car safety, saving hundreds of thousands of lives a year. But most of these cars will be sharing data via the web. This raises real security concerns. But just how real is this car hacking threat and how much is hype? Tim Ring finds out, and reports on what security researchers are doing to push car makers to accelerate their drive to take car security seriously. He also asks what car drivers can do to protect themselves and their passengers.

Triboelectric Nanogenerators as a Self-Powered 3D Acceleration Sensor.

A novel self-powered acceleration sensor based on triboelectric nanogenerator is proposed, which consists of an outer transparent shell and an inner mass-spring-damper mechanical system. The PTFE films on the mass surfaces can slide between two aluminum electrodes on an inner wall owing to the acceleration in the axis direction. On the basis of the coupling of triboelectric and electrostatic effects, the potential difference between the two aluminum electrodes is generated in proportion to the mass displacement, which can be used to characterize the acceleration in the axis direction with a detection range from about 13.0 to 40.0 m/s(2) at a sensitivity of 0.289 V·s(2)/m. With the integration of acceleration sensors in three axes, a self-powered 3D acceleration sensor is developed for vector acceleration measurement in any direction. The self-powered 3D acceleration sensor has excellent performance in the stability test, and the output voltages have a little decrease of ∼6% after 4000 cycles. Moreover, the self-powered acceleration sensor can be used to measure high collision acceleration, which has potential practicability in automobile security systems.

IoT 관점에서의 차량 위협 탐지 방안

These days, a conversion of the fast-advancing ICT (Information and Communications Technologies) and the IoT (Internet of Things) has been in progress. However, these conversion Technology could lead to many of the security threat existing in the ICT environment. The security threats of car in the IoT environment could cause the property damage and casualty. There are the inadequate preparations for the car security and the difficulty of detection for the security threats by itself. In this paper, we proposed the decision-making framework for the anomaly detection and found out what are the threats of car in the IoT environment. The discrimination of the factor, path and type of threats from the attack against the car should take priority over the self-inspection and the swift handling of the attack on control system.

Intelligent Car Security System Microcontroller based

Theft attempts and crashing of cars due to careless parking are common issues in unattended public parking lots. This paper presents an intelligent car security system that provides security to the car against theft and crashing in parking lots. The main parts of the system are GSM and GPS modems, Camera, XYZ sensor and Microcontroller. The design focus is to make a highly secure, flexible, reliable and cost effective system. Any crash that happens to the car in the parking lots is immediately communicated to the owner through SMS. Motion sensors detect any vibration such as theft or crash and instantly capture the picture of the incident. The system also saves the picture of any damage caused to the vehicle rendering it as an evidence for further investigation in future. A prototype of the proposed system has been implemented. The test results prove that the system can monitor the parking area of the vehicle, inform the car owner about the status and the location of the car in case of any crash and helps in identifying who is responsible for such an incident by detecting the vibration and taking pictures around the parking area.

Embedded Smart Car Security System on Face Detection

In this proposed embedded car security system, FDS(Face Detection System) is used to detect the face of the driver and compare it with the predefined face. For example, in the night when the car’s owner is sleeping and someone theft the car then FDS obtains images by one tiny web camera which can be hidden easily in somewhere in the car. FDS compares the obtained image with the predefined images if the image doesn’t match, then the information is sent to the owner through MMS. So now owner can obtain the image of the thief in his mobile as well as he can trace the location through GPS. The location of the car as well as its speed can be displayed to the owner through SMS. So by using this system, owner can identify the thief image as well as the location of the car This system prototype is built on the base of one embedded platform in which one SoC named “SEP4020”(works at 100MHz) controls all the processes .Experimental results illuminate the validity of this car security system.
